Lydia and Sam met while in their first year of college in UCLA where Lydia was studying to become a Chef, and Sam was studying Medicine. After years of dating, Sam proposed to her at his graduation! They had a rustic wedding in the autumn, and their 3-week honeymoon in Jakarta. When they got back, Lydia was thrilled to discover that she was pregnant! 9 months later, she gave birth to a beautiful baby boy, whom they decided to call JoshuaBenedict O'Brien 'Josh'.

After Josh turned 2, the pair decided that they wanted another baby in the house, although Lydia wasn't sure she was ready for the process of carrying a child again. This led the them into thinking about alternatives to natural conception, and they decided that they would like to adopt a child. Because the Far East held such special memories for them, they decided to adopt a child from China, settling on a 6-month old baby girl that they deicded to name LouisaAdele O'Brien.

2 years after they adopted their baby girl, the itch was back, Lydia and Sam wanted to make their family bigger again. This time, Lydia felt she was ready for carrying a child and soon enough, she was pregnant again! This time however, there was a surprise in store for them - Lydia was expecting not one, not two, but three babies! Needless to say, the couple were over the moon! Nine months later, three bouncing baby boys arrived to the delighted mother and father. Their names were JasperTevin O'Brien, RoryCaspar O'Brien, and ArgusSorrell O'Brien 'Gus'.

Less than a year after the birth of your newest additions, Lydia got a call from the police in the middle of the night - her brother and his wife had been killed in a car accident, leaving behind four girl quads, aged 7. As she and Sam had been named guardians in her brother's will, custody is granted to the O'Briens and the girls move in almost immediately. With this massive increase to the family, a new house was found in the suburbs of the city that the girls were living in, in order that they wouldn't have to move schools. The girls' names are LyraKirrily Whishaw, Vesper Illyria Whishaw, GeorgianaHalcyon Whishaw and CaterinaAmoret Whishaw.

With the four girls being added to the family as well as the year-old triplets, Lydia and Sam decided that the family had to settle back down into normality before any more children were added. Three years pass before they think that their large family are ready for yet more additions, but soon the time comes, and they felt that they should start trying for children again. It's a year before a child is conceived, although once it is, there are no problems, and nine months down the line, Lydia gave birth to three lovely triplet girls, whom they call DaisyAlis O'Brien, RebeccaPhoebe O'Brien and TemperanceAdalie O'Brien 'Imp'.
